Flow Cytometry analysis of U-87 cells using anti-CTNNA1 antibody (PB9137).
Overlay histogram showing U-87 cells stained with PB9137 (Blue line). To facilitate intracellular staining, cells were fixed with 4% paraformaldehyde and permeabilized with permeabilization buffer. The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-CTNNA1 Antibody (PB9137,1μg/1x106 cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-rabbit IgG (BA1127, 5-10μg/1x106 cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1μg/1x106) used under the same conditions. Unlabelled sample without incubation with primary antibody and secondary antibody (Red line) was used as a blank control.

Background of CTNNA1
CTNNA1, also known as Catenin alpha-1 or Catenin (cadherin-associated protein), alpha 1, is a protein that in humans is encoded by the CTNNA1 gene. It is mapped to 5q31.2. When surface epithelium CTNNA1 was ablated, hair follicle development was blocked and epidermal morphogenesis was dramatically affected, with defects in adherens junction formation, intercellular adhesion, and epithelial polarity. In vitro, CTNNA1 null keratinocytes were poorly contact inhibited and grew rapidly. These differences were not dependent upon intercellular adhesion and were in marked contrast to keratinocytes conditionally null for another essential intercellular adhesion protein, desmoplakin Knockout keratinocytes exhibited sustained activation of the Ras-MAPK cascade due to aberrations in growth factor responses. It is concluded that features of precancerous lesions often attributed to defects in cell cycle regulatory genes can be generated by compromising the function of CTNNA1.

Antibody Homology Across Species
The results generated by this homology analysis tool for commonly used animal species are shown below. For unlisted species, please refer to the homology analysis between the immunogen sequence and the corresponding species.
A homology of ≥90% is recommended. Generally, higher homology indicates a greater potential for cross-species reactivity. However, protein expression levels may vary among different species, tissues, and cell types. Therefore, the homology analysis results are for reference only and do not guarantee antibody cross-reactivity or experimental performance.
